ADJUSTABLE cums PLATE FOR FUR MACHINES Filed March 27, 1961 JNVENTORPAUL MlSOV E ATTORNEY United States Patent 3,099,235 ADJUSTABLE GUIDEPLATE FOR IF UR MACHENES Paul Misove, 9 Lincoln Road, Great Neck, NDY.Filed Mar. 27, 1961, Ser. No. 98,367 2 Claims. ((Jl. 1l22t)) Thisinvention relates generally to sewing machines of the type known asover-seaming machines for stitching furs, and relates more particularlyto an improved attachment for supporting the furs to be stitched inproper position .with respect to the stitching head while the furs arebeing fed through the machine.

In such a machine it is the usual practice to support and feed the fursto be stitched through the machine in substantially a vertical plane bymeans of a pair of discs or wheels, one of which is rotatable.Ordinarily, however, it is difficult in practice to so guide the fursthat the stitching and seaming is not spoiled in appearance.

Another objectionable feature of the seaming operation as ordinarilyperformed is that the seam it produces is uniformly too heavy dueprimarily to the fact that the needle of the machine passes through thefurs at a point too far removed from the edge thereof.

Still another objectionable feature is the difliculty encountered duringthe seaming and stitching operation in maintaining the furs in properposition such that the edges thereof which are to be oversearned lieconstantly in the same horizontal plane, the tendency being for the fursto drop as they are fed through the machine with the result that theneedle either passes too close to the edges of the furs or else passesentirely over the edges of the furs, thus spoiling the seam.

It is among the general objects of this invention to obviate and avoidthe foregoing objectionable features and difficulties of manufacture bythe provision of cooperating parts which are operative to maintain thefurs in proper stitching position as they are being fed through themachine, these parts being relatively so arranged that the resultantseam is uniformly neat in appearance and substantially flat. A specificobject of the invention is the provision of a horizontally disposedpressure member arranged for slidable movement in the needle guide,which member cooperates with the stitch finger member to maintain thefurs in proper stitching position.

Another object is to provide an attachment for the guide plate thatserves to guide the edge of the fur ma terial and to prevent irregularstitching in over-seaming.

A further object is to provide an attachment of this kind that isadjustable for adjusting the depth of the stitch from the edges of thefurs.

It is also an object of the invention to provide an attachment of thiskind for a sewing machine that is easily installed on a machine, issimple in construction and economical to manufacture and is highlyefiicient for the purposes intended.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 7 is a side view of the attachment on a smaller scale.

FIG. 8 is a cross-sectional view taken on the line 88 of FIG. 2.

Referring now in detail to the drawings, in FIG. 1 there is shown aportion of a conventional fur sewing machine including idler and feeddiscs or wheels 10 and 12, respectively, mounted on base 14. The discsor wheels have cooperating peripheral surfaces between which the skinsto be stitched or seamed are clamped and fed through the machine insubstantially a vertical plane, the upper edges of the skins extending aslight distance above the top plane of the feed discs or wheels.

The threaded needle 16 of the machine is carried by the needle bar 18,this bar being mounted for horizontal reciprocable movement such thatthe needle is caused to move back and forth across the common tangentialplane and above the upper edges of the wheels 10* and 12, with theresult that the needle will be caused to penetrate the edges of theskins extending above the feed wheels. Cooperating :with the needle 16in the usual manner is a looper 20. The needle and looper are actuatedby suitable mechanism in housing 22.

In accordance with the present invention, a guide plate assembly 24 ispositioned on top of the idler disc or wheel 10 and comprises a mainbottom plate portion 26 and an auxiliary top plate portion 28. The mainplate portion 26 has an elongated rectangular-shaped body 30 with acentral longitudinal groove 32 extending along the top surface thereoffor intermittently receiving the point of the needle 16 as it passesthrough the skins. The bottom surface of the main plate portion at oneend is enlarged as indicated at 34. At the opposite end the bottomsurface is cut away forming an arcuate shoulder 38, said cutaway portionproviding a clearance for the rim of the disc 12. Groove 3 2. intersectsthe remainder of the material of said opposite end. The top surface ofthe main plate portion 26 is flat and smooth to receive and support theauxiliary top plate portion 23. A threaded hole 40 is formed in theenlarged end of the main plate portion 26.

The top plate portion 28 has a short fiat rectangularshaped body withone end rounded and the other end straight. The body is approximatelyone-half the length of the body of the main plate portion 26. The bodyof plate port-ion 28 seats on the top surface of the rounded end of mainplate body 26 with its rounded end edge registering with the rounded endedge of the plate 26. The straight end of the body of plate portion 2-8is formed with a groove 46 aligned with and forming an extension of thegroove 32 in main plate portion 26. A smooth-walled hole 48 is formed inthe body in alignment with the groove 46, which hole 48 is in registerwith the hole 40 in the main plate portion 26 for receiving a headed andthreaded bolt 50 extending through the registering holes securing theplate portions to each other.

At one side, the top plate portion 28 is enlarged as indicated at 54which enlarged side is formed with an arm 56 extending longitudinallyand forming an extension of the body, positioned along the adjacent sideof body 30 of bottom plate portion 26. The arm 56 is curved at its freeend and is formed with a threaded hole 58- at said end. The enlargedside portion 54- is formed with a narrow slot 60 horizontally disposedas viewed in FIG. 7, extending substantially the length thereof. Anelongated slot -62 is formed in the plate portion 23 which slot a2 isclosed at its ends and communicates with the slot 60 and intersects andopens out through the side of the enlarged portion as indicated at 64.The floor of the slot 60 opposite the side opening 64 is formed with anotch 66 along its outer side edge.

A principal feature of the present invention is an elongated, thin, flatpresser plate 7% slidably fitted in the slot 60 in the top plate portion23. The presser plate is preferably formed of springy metal. Withparticular reference to FIG. 4, plate 70 comprises an elongated, narrow,thin, flat body 72 having straight sides '74 and 76. At one end, theside 76 curves toward the side '74 forming a curved end 78, conformablein shape to the rounded edges of the bodies of the bottom plate portion26 and top plate portion 28. The body 72 at its end opposite the curvedend '78 is enlarged along the side 7d as indicated at 88 and formed inthe center of the enlargement is an elongated slot *82 closed at bothends. The enlargement is formed with an extension along the edge 74forming a narrow presser finger 84. A finger piece of knob 86 extendsfrom the surface of the body adjacent the curved end thereof formanipulating the presser plate.

The presser plate '76 is substantially the length of the body of the topplate portion 28 and the arm 56 so that when the presser plate is inposition, as shown in FIGS. 2 and 3, in the slot 60, the finger piece 86extends through and outwardly of the slot 62 in the top plate portion 28and is adapted to ride therealong, and the elongated slot 82 is over thethreaded hole 58 in the arm 56 of the top plate portion 28. A headed andthreaded bolt 88 passing through slot 82 is anchored in the hole 53 andguides the sliding movements of the presser plate and holds the presserplate in moved adjusted position. The finger piece 86 engaging the endsof the slot 62 limits the movements of the presser plate, the notch 66providing a clearance for the bottom end or" the finger piece.

In operation, the presser plate 70 is moved by means of the finger piece86 outwardly of the main guide plate portion 26 over the rim of thedrive wheel 12. A pair of skins 90 and 92 to be sewed and having fur 94are fed to the discs or wheels 16 and 12 with the fur sides abutting tobe pressed together for stitching. The edges of the skins engage theunderside of the presser finger as as they pass between the discs orwheels thereby guiding the movement of the fur material so as to preventirregular stitching, and especially when overseaming. The finger 84 isdisposed sufiiciently close to the flange of the feed wheel 12 toprevent the fur as well as the material from lapping over the face ofthe feed wheel and thereby further avoiding irregular stitching.

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and that various changes andmodifications may be made Within the scope of the invention as definedin the appended claims.
